Grotek's Monster Bloom is a fertilizer that be used in the flowering phase providing the plant with all the nutrients it needs to increase its flowering and therefore its final result.

Monster Bloom, by the Canadian Company Grotek, is undoubtedly one of the most used and classic fertilizers in the United States, and one of the best sellers in its country of origin. This is not surprising considering the excellent results it provides to all cannabis growers that have used it.

But, what properties and benefits make Monster Bloom become a "bestseller"?

We will start by talking about the stimulating effect that this fertilizer has on plants. In this sense, the high concentration of phosphorus, which stimulates the roots of the plant during its period of flowering, make crops to be full of flowers in the middle of its development, that is particularly noteworthy.

On the other hand, Monster Bloom also provides an important amount of potassium, which makes the plant do a better process of photosynthesis, generating a greater amount of starch in all tissues of the plant.
In addition, Monster Bloom also boosts the flavor of marijuana buds, something that your palate and mind will appreciate. However, you should stop using it two weeks before the end of the flowering stage.

For both, hydroponic and soil crops, the following dosage is recommended: 6 grams of Monster Bloom per 19 litres of irrigation water.

A product that is perfectly compatible with Heavy Bud by Grotek, to enhance the final results in your crop.

Dosage and usage of Monster Bloom by Grotek:

Add 0.3g of Monster Bloomper litre of water. That’s 3 grams per 10 litres.
Use it during the fattening stage only. If used when the flowering has just begun, it can slow your plants.
down since they could be over-fertilized due to the strong concentration of PK. Use it from the 4th or 5th week, depending on the varieties, until 10 days before the harvest.

Composition of Monster Bloom by Grotek:

NPK 0-50-30 (w/w)
